【Unused, with Batteries】Wireless Microphone (CWT807H PLUS) 【Description】 I purchased this for use in a live music venue, but due to my lack of knowledge, I realized that peripheral devices such as a "receiver" were required separately. I have kept it stored without ever using it. As I have no plans to use it in the future, I would like to sell it to someone who is knowledgeable. • Condition: Unused, opened. • Accessories: Everything shown in the photos. • Bonus: I will send it with new batteries installed, so you can use it immediately if you have compatible equipment. ※ I do not have expert knowledge, so I cannot answer detailed specifications. Please check the official website of "Sound House" etc. for product details. ※ Please consider that this is an unused item, but it has been in someone's possession once. The following is a quote from the official website ↓ (Quote here) "A set of headset microphone and transmitter for the CW-Plus series. It can be used in combination with receivers such as CWR802PLUS."
